Well I had “given” the tracker to my son, and I reinstalled it recently on my main PC. So yes it was working on my setup (a few months ago), and I only did the update when I reconnected the tracker (in preparation of Deus Ex, I must admit 🙂 )
I tried the calibration again with no light, no success, same behaviour
Regards
Sidenote: where can I buy additionnal mounting plate for the tracker ?
